Question

我有这样的Grafana指标：

SELECT
  UNIX_TIMESTAMP(time) as time_sec,
  sum(average_hashrate_eth) as value,
  'total hashrate' as metric
FROM status_rig
group by time;

发出如下警告：

WHEN last()

的

query(A, 5m, now) IS BELOW 800

如果此查询仅低于800超过4分钟，我该如何才能提醒？

感谢。

Answer 1

您只需更新警报配置即可使用：

当查询的max（）（A，4m，现在）低于800时

Answer 2

假设度量的时间频率为60秒，时间为DATETIME类型。

试试这个：

  SELECT
   UNIX_TIMESTAMP(time) as time_sec,
   SUM(case when average_hashrate_eth < 800 THEN 1 ELSE 0 END) as counter,
   SUM(average_hashrate_eth) as value,
   'total hashrate' as metric
  FROM status_rig
  WHERE time between (now()-interval 5 minute) and now()
  HAVING counter>=5;

如果价值保持在800以下，这将为您提供当前时间最后五分钟average_hashrate_eth的总和

将Grafana配置为仅在查询匹配超过4分钟时发出警报
